Are "sunblocks" and "sunscreens" the same thing?
No. They both provide sun- protection for the skin, but they use different ingredients and mechanisms in achieving that protection. A "sunblock" most commonly uses zinc oxide or titanium oxide to "block" the sun's harmful rays from penetrating the skin by reflecting it. A "sunscreen" uses minerals and other ingredients to absorb the sun's harmful rays once it gets into the layers of the skin. This helps mitigate sun damage to the skin. Sunscreens are easier to wear than sunblocks as they readily absorb into the skin and do not leave a whitish residue. However, sunblocks are more advantageous in that they do not allow penetration of the sun into skin. Sunblocks are good for long periods or extreme sun exposure, swimming and sports.
What is "SPF"?
SPF stands for "sun protection factor". The SPF reveals the amount of sunburn protection that a sunscreen can provide an average user, when applied correctly. The recommended SPF No is 30 and above. The SPF rating is calculated by comparing the amount of time needed to produce a sunburn on protected skin to the amount of time needed to cause a sunburn on unprotected skin. Let us take for instance a fair-skinned person who would normally turn red after 10 minutes in the sun. Ten minutes is their "initial burning time." If that person uses a sunscreen with SPF 2, it takes 20 minutes in the sun for that person's skin to turn red. Now, if that person uses a sunscreen with SPF 15, it multiplies the initial burning time by 15, so it takes 150 minutes, or 2 and half hours, for that person's skin to turn red.
What are UVB and UVA rays?
Sunlight has a profound effect on the skin causing premature skin aging, skin cancer, and a host of skin changes. Exposure to ultraviolet light, UVA or UVB, from sunlight accounts for 90% of the symptoms of premature skin aging. Many skin changes that were commonly believed to be due to aging, such as easy bruising, are actually a result of prolonged exposure to UV radiation. The sun gives off ultraviolet radiation that we divide into categories based on the wavelength.
- UVC - 100 to 290 nm
- UVB - 290 to 320 nm
- UVA - 320 to 400 nm
The sun's radiation accounts for 90% of skin aging and skin cancers. UVA rays are responsible for the aging effect of the sun as it penetrates deeper and intensity of UVA radiation is more constant than UVB; overexposure to UVA rays can cause skin cancer. However, it is not filtered by glass. UVB rays are responsible for sunburns and skin cancer.
Can I use my sunscreen for my face on my body too?
Yes. However, sunscreens can be expensive and sunscreens developed especially for the face, even more so: they must use a more advanced science and expensive ingredients because the face tends to be more sensitive than other parts of the body. This is especially true after facial treatments or surgery of any kind. General advice: It is better to use a specially formulated sunscreen for your face on the rest of your body, if you have to, than to use a general allover sunscreen on you face.
Do you need water resistant or waterproof Sunscreens?
It really depends on your activities. If you are looking for a sunscreen to use while in the water, choose a sunscreen that is "waterproof" or "water resistant."
"Waterproof" sunscreen should provide protection in the water for 80 minutes, while "water resistant" provides only 40 minutes of protection.
So why FALLENE?
Well, Fallene sunblocks have all the relevant ingredients to help to protect the harmful ultraviolet rays. The texture is smooth and has an advantage over most sunblocks as they are skin tone colour and the total block can be mixed with the colour adjusters to customize the colour that you want. The price is reasonable and there is water resistant version which is good for people who loves the sea or water sports. If you want to find more information, you are welcome to contact us.
